Step 1Heat the oven to 300 degrees. Line a rimmed baking sheet with parchment paper.
Step 2In a large bowl, stir together the oats, chia seeds and salt.
Step 3Melt the butter using a microwave or in a small pot on the stovetop. Stir in the honey, mixing until blended, then pour the honey-butter into the bowl of oats. Mix well.
Step 4Transfer the mixture to the prepared baking sheet, spreading evenly and pressing down with the back of a spoon to encourage the granola to form clusters. Bake for 15 minutes, stir the granola and press it down once again, then continue to bake until golden brown, about 20 minutes. Cool on the baking sheet. Store the granola in an airtight container at room temperature for up to one month.
